CLEVlS FOR WHIFFLETREES.

SPECIFICATION forming part of Letters Fatent No. 634,926, dated October17, 1899.

Application filed March 23,1898.

To all whom it may concern.-

Be it known that I, WILLIAM H. WELLS, a citizen of the United States,residing at Seville, in the county of Gratiot and State of Michigan,have invented certain new and useful Improvements in Center Olevises forWhiffletrees, of which the following is a specification.

Figure l is a perspective view showing the application of the inventionand attachments e and f. Fig. 2 is a cross-section showing swivel in thesocket of the socket-plate aand attachments e and g; Fig. 3, anelevation of the swivel.

The object of this invention is to' provide a center clevis forwhiffletrees, either single or double, which will at all times givefree'play thereto, thus preventing the twisting of clevises andsplitting and breaking of the wood, and, further, to provide a cheap andpractical attachment to a doubletree or singletree adapted forconnection to removable hooks and clevises by means of the removable pinor bolt d, and is specially useful for hauling or dragging by means of achain and is for the purpose of preventing the twisting or kinkingthereof; yet the practical utility of this invention in manifold wayswill be at once obvious to any teamster, for the grab-hook and cleviscan remain attached to the evener when the team is hitched to a wagon,sleigh, or other vehicle, and thereby the team can be quicklytransferred to a plow, road-scraper, or a chain for hauling logs, stone,or stumps.

In plowing and scraping the attachments e and plow-clevis fare used,thus permitting the change from plow to road-scraper, or vice versa, inthe quickest possible time.

By means of the movable pin 01 hooks or clevises may be attached asbecomes necessary.

The socket-plate a is made in one piece of cast malleable iron, thecenter larger and heavier and curving outwardly in a semicircular shape,with a concave recess in the side next .to the whiffletree large enoughto receive the ball-shaped bur c, and has a longitudinal slot m throughthe semicircular center on theopposite side, as shown in Figs. 1 and 2,

m and receive the bur c'screwed or riveted to it, as shown in drawings.

The bur c is made with a convex surface to fit the concave recess in thesocket-plate a, having a hole through the center to receive the shank ofthe swivel-bolt I) through the longitudinal slot 011.

The.plow-clevis fand hook g are so constructed as to fit and fill theinside of the clevis part of bolt 1?, either of which may be combinedwith attachments b and e by means of the removable pin d.

Olevis c is so constructed as to fit and clasp the outside of theclevis-head of bolt 6.

The special combination of the socket-plate a and swivel-bolt b with anytwoof these attachments by the movable pin cl, as represented in thedrawings, provides a tool that is new, useful, cheap, practicable, and.durable. 1

I am aware that hooks with heads working in a socket, and thus made toswivel, have been invented to meet the demand of a coupling to change ateam from wagon to plow,

or vice versa; but none of them are practical, for the hooks of thatkind,-so faras patented, are of such shape as to become unhooked soeasily that they are of no utility whatever.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination of the whiffletree 7c, the socket-plate a having theslot m with the clevis-shaped swivel-bolt I) having the removable pin dadapted to removable hooks and chains, and the ball-shaped head 0, beingriveted or screwed to the shank of said bolt 1) after it is entered intothe slot m substantially as described. 4

In testimony whereof I affix my signature in presence of two witnesses.
